Description

technical field [0001] The invention relates to the field of biotechnology, more specifically, the invention relates to a kit for extracting serum virus nucleic acid by biological nanometer magnetic beads. Background technique [0002] In recent years, with the rapid development of biotechnology, functional magnetic beads have become more and more widely used, and have been gradually applied to the separation and purification of various biological substances such as nucleic acids (RNA and DNA). Compared with the traditional non-magnetic method, its steps are simple, no centrifugation is required, and manual errors can be reduced. In addition, as a research hotspot of nucleic acid extraction media, the magnetic bead method also has the advantages of high sensitivity, rapidity and reproducibility. In view of the manipulability of magnetic beads under electromagnetic fields, they have broad application prospects in high-throughput screening platforms. In addition, the semi-au...

AI Technical Summary

Problems solved by technology

[0003] Although the extraction of nucleic acid by magnetic beads has important medical application value, the stability of RNA nucleic acid is lower than that of DNA, which makes the extraction of RNA more complicated than that of DNA.

In addition, the existing kits have reagent bottles that are not placed stably, resulting in low test efficiency

Therefore, the kits for extracting RNA in the prior art still need to be improved in terms of operational convenience and efficiency improvement
